Moderna data indicates COVID booster is effective against omicron


New data released by Moderna indicated that its updated COVID-19 boosters provide enhanced protection against the omicron variant.

His data showed that the booster provides a five-fold increase in antibodies for those who have already been infected. For those with no previous infection, the increase was more than six times greater.

The data indicated a strong immune response three months after being boosted.

“We are pleased to see that our two bivalent booster vaccine candidates provide superior protection against Omicron BA.4/BA.5 variants compared to our original booster, which is encouraging given that COVID- 19 remains a leading cause of hospitalization and death worldwide,” said Stéphane Bancel, CEO of Moderna. “Our bivalent recalls also show, in research tests, neutralizing activity against BQ.1.1, a increasingly dominant emerging variant, confirming that updated vaccines have the potential to offer protection as the virus continues to rapidly evolve to evade our immunity.”

Pfizer had previously announced that its booster candidates also provided a strong response to omicron.

The Centers for Disease Control and Prevention recommends boosters for people age 5 and older with 2 previous COVID-19 injections.

So far, 10.1% of people age 5 and older have received an update, the CDC said.
